The new recognition of fluid responsiveness assessment

Clinically, apart from traditional assessment method such as volume expansion (VE) and passive leg experiment (PLR), the procedure that may cause hemodynamic fluctuation during surgery can also assess fluid responsiveness, such as desufflation in laparoscopic surgery, liver compression, and lung recruitment. Besides static pressure indices, increasing attention has been drawn on fluid responsiveness assessed by ultrasound in intensive care unit (ICU) or perioperative in recent years. This article reviewed the latest progress in fluid responsiveness assessment, especially assessment method, monitor indices and cut - off value, and proposed specific recommendations for perioperative fluid therapy. It′s wise for physicians to synthesize different indices and methods when give a assessment of fluid therapy, and part of which need more researches to verify.
